I'm a third-year GI fellow starting to think seriously about board prep for the ABIM gastroenterology certification exam. The ACG review course runs around $800-1,000 depending on format and I'm trying to decide if that's worth it compared to building my own prep from MKSAP, GILearn, and UWorld GI.
My fellowship program covers MKSAP access and I have GILearn through ACG membership, so I'm not starting from scratch. My weak areas are hepatology and small bowel pathology — we see a lot of IBD and colon cancer at my institution but relatively little advanced liver disease outside of transplant cases.
I'm planning to start serious prep about 4 months out and do 1.5-2 hours a day. I've taken ABIM IM boards already and passed at around the 70th percentile so I'm not completely cold to board-style questions, but GI has enough specialty-specific content that I don't want to assume the same approach will work.
Has anyone used the ACG live course or self-study version? And is there a question bank that better matches what's actually on the boards?
UWorld GI question quality is noticeably better than GILearn for board-style reasoning in my opinion. GILearn is great for content review but the questions don't always mimic the clinical vignette format you'll see on the actual exam. Use both but weight your question practice toward UWorld.
4 months at 1.5 hours a day should be more than enough with your IM boards background. The ACG course is better for people who struggle with self-directed studying than for people who already have solid study habits.
Hepatology is a known weak spot for fellows who train at non-transplant centers. NASH cirrhosis staging, portal hypertension management, and HCC surveillance intervals are very heavily tested. I'd allocate 6 full weeks to hepatology even if it feels disproportionate.
Did GILearn plus UWorld GI without the live course and passed comfortably. The ACG course is solid for hepatology specifically — some lectures are genuinely excellent — but if you're budget-conscious the self-study materials cover the same content at your own pace. I'd spend the $800 on extra UWorld months instead.
I went through this exact debate last year as an attending moonlighting through board prep between shifts. Honestly, the ACG course was worth it for me, but mainly because the structured format forced me to actually sit down and review material I kept pushing off. If you're disciplined enough to grind through resources on your own, you can absolutely pass without it. I paired the course lectures with practice sets from acg/questions/gastrointestinal disease diagnosis and management during my lunch breaks and it clicked a lot faster than reading alone.
The real value wasn't the content itself — most of it overlaps with GILearn — it's the pacing. Having deadlines pushed me to stay consistent when my schedule got brutal. That said, $800 is real money. If you're already self-motivated and GILearn plus UWorld is working, don't feel like you're missing something magical.
I took the ACG course last year before sitting for boards and honestly it depends on how you learn. For me the biggest value wasn't the content itself — I knew most of it — it was watching the faculty explain why each wrong answer is wrong. That's the part self-study misses. You can drill UWorld all day and get good at pattern recognition but if you don't understand the reasoning behind why B is wrong versus why C is right, you're going to struggle with the harder questions that are just a little bit off from what you've seen.
That said, if you're disciplined with GILearn and you're actually reviewing your incorrect answers deeply rather than just moving on, you might not need it. It's $800-1000 that I didn't regret but I also know people who passed without it. If you can find a co-fellow to split a recorded version with, that's probably the sweet spot — you still get the explanations without the full hit to your wallet.
